The list author says: "There's a lot of confusion going around regarding what properly counts as 'dubstep'. Part of the problem is that some of the recent artists who have popularized it are very distinct from the artists who forged it. In particular, many of the remixes that are passed off as dubstep on youtube are hard, very busy, and lack subtle changes throughout. Much of this shares the 'grime' -- the dirty feeling of disgust -- which was an early staple of the genre. Yet, it lacks the minimalism and the smooth, laid-back feeling typifying many of the progenitors. Sparse, heavily reverberated percussion with deftly placed tones where empty space plays an important role in the development, is characteristic of this early style of dubstep. Interestingly, this early form is very introspective and contemplative which contrasts starkly with the club-ready, heavy-hitting bass drops of, for example, Rusko and Skrillex. Simplifying, the genre's split between the minimal, atmospheric trend on the one hand, and the devastatingly heavy approach embodied in the more recent and accessible variety. Enjoy."
